Rappelz - In-Depth Creature Guide

At this moment, you still cannot summon the creature yet even if you have succeed. You must form it at the local tamer before you can summon it.
Visit the Tamer/Breeder/Summoner NPC in any of the city (or the Adventure Guide in Trainee Island), and choose 'Creature Formation'.
Now drag the tamed creature card onto an empty slot of the creature forming window. You can have up to 2 slots depending on your Creature Control skill level. Now you can finally summon your creature (About time!). When you form a creature, its name will be rappelz rupees generated. So far there is no way to rename the creature as you wish

Open up the creature window (Alt + R) and select the creature by clicking on the icon of the creature you wish to summon, then use the Summon Creature skill... voila! You have summoned your creature!
You can only summon one creature at a time , even if you can control 2 creatures. When you try to summon another creature while one is already out, the previous one will automatically be recalled after the second one is summoned. You can recall your creature back any time you wish by using the Recall Creature skill.

III. Controlling & Raising

Once you have summoned your creature, it will automatically follow you around wherever you go, but not necessarily aid you automatically. There are 3 default actions you can make your creature take on the action window (Alt + T).

Creature Attack - Creature attacks target by itself. (Alt + Click Target)
Joint Attack - Creature and Characters attacks the target at the same time. Depending on the movement speed, one may start attacking over the other. The monster will first counterattack whoever attacked first, but will eventually attack whoever deals more damage. (Ctrl + Click Target)
Follow - You can leave your creature at one spot and not follow you. You must reactivate it to make it follow you again. (ESC x 3... why three times' I don't know.)
As the creature fights alongside you, it will also gain experience and JP. Yes, the creatures can use skills too! Their stats are permanently fixed however.
It will gain approximately 10% of what you earn when it is summoned, and it will gain only 1% when it is not summoned. Creatures that you own the card but not yet formed or rappelz rupees on your belt will not gain anything.
